VELOCIPEDE.

Application 'filed December It is to be understood, however, that features of the invention are applicable to other types of velocipedes suoli, for example, as adult cycles, or childrens scooters having y a platform onv which the user stands and either With or Without a' supported saddle or seat.

kA particular vobject of the invention is to provide an improved fand simplified means for mounting vin the frame the shaft or spindle carrying the driving pedals, whereby the socketed bottom'bracket 'such as is at present usually employed in the construction of adult cycles is'ieplaced by a channel or U shaped plate, with a consequential reduction in the cost of manufacture.

A further particular object of the present invention is to provide an improved 'and l simplified means providing a rigid and effective adjustable mounting for a pillar'or equivalent member carrying a saclcllmwhich obviates the use of a 'special cast metal socket or tubular supporting' Vframe vand employs a minimum number of 'additional bolts or members' for mounting the socket and rendering it con'tractible. K

A preferred method of carrying the invention into effect is illustrated by the uaccompanying drawings which shoiv a childs 4cycle and in which1 Figure 1 is a perspective vieiv.

Figure 2 is a vertical section.

Figure 3 is a front elevation.

Figure l is a vertical section taken through the centre of the handle 'bar and upper portion of the front fork unit.

Figure 5 is a vertical transverse section through the bottoni bracket.

Figure 6 is a plan vieiv of the seat clip and support.

The cycle illustrated has a forward unit comprising a front Wheel 10 which is mounted in a front fork 11 associated with handle bars 12 and pivotally mounted with respect to ahead 13.

A main framework rigidly associated with the head 13 carries a rear Wheel 14, an up- 31, 1925. serial no. y78,643.

ivardly extending frame or support'for a saddle 15,` and abracket orinounting for driving pedals 16.

rEhe main framework-is formed by means of a pair of longitudinal members or girders which are placed side by side and have vtheir forward ends secured rigiuiyi oy means of rivets 21 on `either side of a lug 22 formed integrally with vthe head .13.

These girder members 20 'are in thereiiarn'-4 ple illustrated formed from solid-'metalofI shaped cross'section, but it iste be understood that they may lbeof any gotheiwcross section and Veither solid or tubular. members 2O diverge Lslightly towards the rear and at theirrearward extremities are slotted for receiving the spindle-23 of the rearv Wheel.

Intermediately lof their en'dsthel girder members 20 are riveted to# the flanges ..25

of a plate 26 of inverted U shape :which forms' part of the bottom bracket of the cycle. The* members 2O 4are riveted tothe :outer faces of the flanges andnear their upper ends. Through a hole in theflovver Eendiof each of the flanges 25 there -is passed aislrortlength of tube '27 which" may bel brazedinto position or otherwise secured as found convenient. This tube 27 forms a bearing for a transverse shaft 28 on the lends of'tvhich are mounted pedal `cranks 29. `@ne endro'ff the shaft also carries the usual chain sprocket Wheel 30.

A second plate of erect U shaped form has its transverse yor web portion "36 riveted to the transverse orfiveb lportion '37 of the plate 26. A ybolt`38 carrying'` a nut 39 passes through the flanges 40 of this :platte 35 and also passes thro-ugh the-rearward eX- tremities of a pair of longitudinal sti'i'uts il vvliicli are located side by side and above the members 20. The forward 'extremities of these struts 41 aresecured by a rivet 42 to either side of a lug 113 on the head ,13. 'The bolt 38 also passes through the lower extremities oftivo upwardly extending mermbers 45 Which form the saddle support in conjunction with a further pair of upwardly extending members 46 which have `their lower extremities slotted and in engagement with the rear spindle 23.

The upper extremities of the members S45 and 46 converge after the manner of;A a pyramid and are connected by-means of a The bolt and nut 47 which passes through them. A plate 48 is bent so as to `term a cylindrical or split socket 49 which has flanges 50 extending from the split. These iianges are located between the upper extremities of the members 45 and 46, and the bolt 47 passes through them. A second bolt 51 also passes through the upper extremities of the members 45 and through the ilanges 50.

The saddle 15 is mounted upon an angular shaped rod 59J in any suitable or known manner, and the lower portion of this rod passes through the socket 49 and may be clamped tightly therein when in the con rectly adjusted position by tightening the bolts and nuts 47 and 51.

The members 40, 45 and 46 are all solid, and, with the exception otl their flattened extremities7 are of D shaped cross section. It is to be understood, however, that they may be made of other shaped cross section and either solid or tubular as desired.

A rear mudguard 55 is secured in position at its rear extremity by supporting members 5G which are associated with the rear spindle 23. rhe forward extremity of the mudguard is secured to a supporting rod 57 which has a pair of nuts 5S engaging either face of the mudguard. The forward end of the rod 57 is curled to form an eye and is secured to the undertace of the transverse or web portion ot the plate 26 by means of a screw 59. A front mudguard 60 has its lower end secured by supporting members 61, while its upper end is fastened between the front fork.

The body port-ion of the head 18 is formed by a solid rod-like portion which has either end provided with a conical bearing face GG. These faces 66 are adapted to engage in bearing recesses associated with transverse bracing members G7 which extend between a pair of upward extensions ot the front fork 11.
